TECHNOLOGY
Rogue DNA’s patent-pending RDNA technology combines hardware document scanners with software which interprets and encodes the information retrieved. It is currently designed to work with documents such as paper, card, and plastic (including polycarbonates). The system uses optical/electronic technology to identify the three-dimensional composition of a selected area or areas of a document. As the structure of the material is a totally different pattern for every location on every document, RDNA can provide absolute security in a manner that is non-invasive and inexpensive to implement. If a document is copied, the copy will be on a different piece of material, with a different pattern.

During the scanning process multiple beams of concentrated light at different frequencies penetrate the document at specific angles. A combination of different light sources is used, each highlighting different characteristics of the document. From the reflections RDNA decoding circuitry can determine the pattern of the underlying composition.
The resulting data is converted using RDNA processes into a unique numeric string. This is then encrypted. The resulting digital string represents the unique “DNA” or profile of the document. This string cannot be reverse-engineered back to the document.

Standard light sources include red/ green/ blue, UV, near-infra-red and infra-red. As different documents and materials respond best to different frequencies, the user can experiment with them individually or together to determine the optimal combination for any particular document.
Visual representation of a match or mismatch is provided graphically or numerically. In the following graphs the progress past the scan-head in a swipe scanner is shown on the x-axis, while the feedback from the red sensor is on the y-axis. The graph for the Registration scan is shown in red, while the subsequent Verification scan is shown graphically in green. A tolerance setting allows mis-feeds, paper damage, etc, to be accommodated to a defined degree.
The graph below shows the Registration and Verification scans of the same document under red light.
The following graph shows the feedback from two different documents. These are clearly different and the graph identifies them as such.
